Auto baking the indirect lighting of irradiance volumes with animation?
According to Blender at 
https://docs.blender.org/manual/en/latest/render/eevee/render_settings/indirect_lighting.html in paragraph 3:


  As of now the light cache is static and needs to be computed before rendering. It cannot be updated per frame (unless via scripting). This limitation is being worked on and will be removed in future versions.
